PAPIER-ROLL PRGTECTOR.

Application filed March 30, 1914.

To all whom it may concern Be it known that I, i/VILLARD A. SCHWARTZ, acitizen of the United States, residing at Los Angeles, in the county ofLos Angeles, State of California, have invented new and usefulImprovements in Paper-Roll Protectors, of which the following is aspecitication.

rIhis invention relates to a paper r'oll protector. i

In the transportation of largerolls of paper such as are employed inprinting newspapers and the like, many rolls are damaged and renderedunfit for feeding to the press by reason of their bursting as sometimesoccurs in unloading, by reason of the great weight of the rolls and theinternal pressure set up in shifting them from place to place.

It is the object of this invention to pre vent the above difficulties byproviding a means for binding the rolls to insure them against burstingand also protect their edges against mutilation.

Another object is to provide a binder for paper rolls which can bereadily attached to and removed from the rolls and used a number oftimes.

A further object is to provide a detachable roll binder which can beadjusted to rolls of various sizes.

The invention primarily resides in adjustable hoops for engaging andclamping the peripheral ends of the paper roll, and means for adjustablyconnecting the end straps together on opposite sides of the roll to bindthe roll longitudinally.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the invention showing it as applied.Fig. 2 is a detail in elevation showing the adjustable construction ofthe end hoops. Fig. 3 is a detail vertical section on the line 3-3 ofFig. 2. Fig. 4 is a detail in elevation of theV Patented Q17 an. 2.6,121 5.

diameter and of considerable weight. These rolls in being handled andtransported from place to place are frequently damaged by bursting, andby the mutilation of the peripheral edges at its ends.

The present invention resides in a device for binding the ends of theroll 10 and for securely holding the binding means in place, and at thesame time bind the roll longitudinally, and includes a pair of hoops 1land 12 which engage the ends of the roll, and are connected together bystraps 18 and 1A eX- tending longitudinally of the roll in oppositesides thereof. The hoops 11 and 12 are formed of two separablesemi-circular members 15 and 16 which are adjustably connected togetherat one end, and detachably connected together at the opposite ends.

rFhe adjustable connection of the members l5 and 16 is particularlyillustrated in Figs. 2 and 3 and comprises a. strap 17 rigidly mountedon the member 16 by means of rivets 18, which strap is designed toengage the free end of the member 15, and to retain perforations 19 inthe latter in engagement with lugs 20 on the member 16. A series ofperforations 19 are provided in the member 15 and are arranged in pairsat suitable intervals apart longitudinal thereof. A pair of lugs 20 areprovided on the member 16 and are arranged in such position as tosimultaneously engage a pair of the perforations 19 in the member 15. Bythis construction the diameter of the hoops may be adjusted by varyingthe positions of the over-lapping end of the members 15 and 16 inrelation to each other, and securing them in the adjusted relation bymeans of the perforation 19 and lugs 20.

Mounted on the free end of the member l5 is a rectangular link 21 whichis pivotally connected to the member 15 by turning the end of the latteraround one member of the link 21, and riveting the bent portion of thelink to the main portion thereof by rivets 22 as shown in Fig. 5.Mounted on the outer end of the member 16 is a pair of spaced lugs 23which carry a pivot pin 24, which extends through lugs 23 and throughlugs 25, a clamping arm 26 and forming a pivotal support for the latter.The arm 26 is of a width approximating that of a member 16 and is formedwith a series of angular notches 27 on its upper face, which notchesextend transversely of the arm 26 and are adapted to engage the othermember of the link 21 to connect the outer ends of the members 15 and16, and bind the hoop on the roll 10 as hereinbefore described. Formedon the members 15 and 16 are inturned Hanges 28 which are spaced anysuitable distance apart and are arranged to project over the end of theroll as particularly shown in Fig. 1 to engage the roll and permit ofthe hoops being connected together under strains Without displacement.

The hoop connecting means 13 and 14 is here shown as consisting ofchains 29 and 30 adapted to be detachably connected t0- gether at theirouter ends with their inner ends connected to diagonal extending chains31 and 32, and 33 and 31. The chains 31 and 32 on the chain 29 connectat their outer ends to the members 15 and 16 on the hoop 11 a shortdistance from their ends, and the chains 33 and 34 on the chain 31connect in like manner to the members 15 and 16 of the hoop 12.

The means for clamping the chains 29 and 30 together consist of a plate35 pivoted to the end link of the chain 29, and having a lockable arm 36pivoted at 37 on its outer end, Which arm is formed with transverseinclined channels 3S adapted to engage the end link of the chain 30.

In the operation and application of the invention, the hoops 11 and 12are adjusted to approximately fit the ends of the paper roll byadjusting the lugs 20 in the perfora tions 19; this adjustment beingsuch that the outer ends of the members 15 and 16 Will be normallyspaced a short distance apart. The link 21 is then engaged in one of thenotches 27 on the arm 26 Which is then rocked outwardly and over thepivot pin 24: to the opposite side thereof, thereby drawing the outerends of the members 15 and 16 toward each other, and tightly binding thehoop in place on the end of the roll. The notches 27 are of such depththat when the arm 26 is moved to its clamped position as shown in Fig.5, the engagement of the notches with the link 21 will dispose the linkout of alinement With the pivot pin 24: on the inner side of the latterin such manner that the arm 26 Will be normally retained in itsinnermost position. When the hoops 11 and 12 have been thus secured tothe ends of the roll the straps or chains 29 and 30 are connectedtogether by means of the clamping arm 36 which is engaged with the endlink of the chain 30 and swung to the opposite side of the pivot 33 inthe position shown in Fig. 7, thus drawing the chains 29 and 30 togetherin a taut condition, and thereby exerting a pull on the hoops 11 and 12to effectively bind the roll 10 longitudinally.

It is manifest that any number of the binding straps 13 and 111 may beapplied around the periphery of the roll 10 as occasion may require.Preferably the hoops 11 and 12 are formed of sheet metal and the straps13 and 14 are formed of metallic chains, but it is manifest that othermaterials may be substituted therefore as cccasion may require, forinstance, the hoops and straps may be formed of leather or similarmaterial.

l/Vhat I claim is:

1. A paper roll binder, comprising end engaging hoops and means forconnecting said hoops together to bind the roll longitudinally.

2. A paper roll binder, comprising a pair of adjustable hoops adapted toengage the ends of a paper roll, means for clamping said hoops to bindthe roll peripherally, and means for connecting the end hoops to* getherto bind the rcli longitudinally.

3. A paper roll binder, comprising apair of hoops formed of separablemembers adapted to be adjustably connected together, and having meansfor clamping the members together on the end of a paper roll, means onthe hoop members for engaging the end of the roll, and adjustable strapsconnecting the end hoops together by means of which the roll can bebound longitudinally.

In Witness that I claim the foregoing I have hereunto subscribed my namethis 20th day of February 1914i.
